| description | Multi-Carrier Code Division Multiple Access (MC-CDMA) was proposed to improve capacities of wireless networks. Instead of increasing the data transmission rates of wireless links, we propose to assign independent data streams obtained by MC-CDMA for transmitting up-link and down-link traffic separately in order to eliminate the hidden-node and exposed-node problems between co-channel BSSs in WLANs. Simulations show that our scheme can improve network throughputs by 106% in an exposed-node scenario and by 113% in a hidden-node scenario. We also consider the hardware and MAC requirements of our scheme under different settings of physical carrier sensing range. We believe this is a first paper in the literature to assign MC-CDMA generated data streams in WLANs so as to mitigate the hidden-node and exposed-node problems. © 2007 IEEE. |
